What can I say, mpd is just the best I've found. :)

Please see my and Dave's previous comments: you can remux your raw AAC
bitstream into an M4A (which is the same thing as MP4, just renamed
for convenience) container without reencoding.

YouTube basically gives you nothing (because you're meant to be
showing that blog of data in your browser, not giving it to other
software to play with).

I just use ffmpeg to tag. (ffmpeg -acodec copy -metadata foo=bar etc.)
Some people like AtomicParsley. Whatever works for you.
